Genes affected

ST7 (HGNC:11351): (suppression of tumorigenicity 7) The gene for this product maps to a region on chromosome 7 identified as an autism-susceptibility locus. Mutation screening of the entire coding region in autistic individuals failed to identify phenotype-specific variants, suggesting that coding mutations for this gene are unlikely to be involved in the etiology of autism. The function of this gene product has not been determined. Transcript variants encoding different isoforms of this protein have been described. [provided by RefSeq, Jul 2008]

The c.932G>A (p.R311K) alteration is located in exon 9 (coding exon 9) of the ST7 gene. This alteration results from a G to A substitution at nucleotide position 932, causing the arginine (R) at amino acid position 311 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
